I, too, have noticed the same go to bed order. Usually, my teenagers are the ones who like to stay out late. The same ones are the first to roost way before it gets somewhat dark. My 12 week old just recently has begun to roost on her own.8 weeks old is still a little young to expect them to always go reliably into the coop at night. At that age, they can be like stubborn little kids. I would keep shoving them into the coop at night until they get it. It could be their personalities too. My flock seems to go in their coops in the same order every night with the same 3 girls lagging far behind all the others. We don't have an automatic door so I feel like many nights I am chanting Go to bed, go to bed as I collect the feeders and prepare to close up the coops. They have a secure run for evenings and they do go to bed on their own if I can't get out to bring in the food until after dark.
Your coop is a tiny bit undersized for the standard of 4 sq ft per bird, but our flock can choose between 2 coops and have sorted themselves to 7 birds in a 4x6 coop without bedtime issues![]()
